The expansion of the Universe
Ragged writes:
with time the universe is expandinig at a faster rate, and all the objects within the universe get further away from each other at a faster rate and so on.
It's not so much to do with time as distance. On the line below, the numbers represent galaxies, and the dashes represent a unit of distance in the space between the galaxies. Together, the numbers and dashes are the Universe.
1---2---3---4---5
Now, if space expands by eight dashes over some period of time, the Universe will look like this:
1-----2-----3-----4-----5
Notice that galaxy 5, which was always far from galaxy 1, is now eight units of space farther from galaxy 1; but galaxy 2, which was rather close to galaxy 1 to begin with, is now only two units of space farther from galaxy 1.
So with time any two galaxies in the Universe will go away from each other at a faster rate, but it's the distance which determines that rate.

What has been done to prove that every point in space was "born" in the big bang rather than the big bang occurring at a point in space.
Nothing There is no need.
The observed uniformity of the Cosmic Microwave Background Radiation is pretty compelling, isn't it?
